Persistent acid-fast bacilli following intravesical bacillus Calmette-Guerin.

Intravesical bacillus Calmette-Guerin immunotherapy has great efficacy in the treatment of superficial transitional cell carcinoma of the bladder. We report a case of persistent acid-fast bacilli contained within granulomas of the bladder, prostate and epididymides 1 year after treatment with intravesical bacillus Calmette-Guerin. Although commonly encountered immediately after therapy, there are no reported cases of persistent acid-fast bacilli following intravesical administration of bacillus Calmette-Guerin.
